Definitions
- the present invention relates, in general, to a method for optimizing the quantity of EGR (burnt gases recycled externally) applied to a compression ignition combustion engine.
- the invention relates to a method for controlling a heat engine with cyclic operation such as a direct injection diesel engine, comprising in particular a combustion chamber, means for injecting fuel into the chamber, means for admission to selectively admit a gaseous oxidant containing air into the chamber, exhaust means for selectively authorizing the exhaust of burnt gases out of the chamber and recycling means including a first flow control means for recycling burnt gases, this flow control means being controlled by a variable control signal [Com], the flow of recycled gas being represented by an increasing function of the value of the control signal, a means of measuring the consumption of the engine fuel.
- a heat engine with cyclic operation such as a direct injection diesel engine, comprising in particular a combustion chamber, means for injecting fuel into the chamber, means for admission to selectively admit a gaseous oxidant containing air into the chamber, exhaust means for selectively authorizing the exhaust of burnt gases out of the chamber and recycling means including a first flow control means for recycling burnt gases, this flow control means being controlled by a variable control signal [Com
- the use of so-called recirculation or EGR gases or recycled gases in the combustion chamber of an alternating engine and more particularly of a compression-ignition engine is well known to those skilled in the art.
- the recycled gases are gases resulting from the combustion of previous cycles and are therefore depleted in oxygen. They are used, mixed with air, to reduce polluting emissions or to control the course of combustion. More precisely, the ignition time of an air / fuel mixture containing recycled gases is greater than that of an equivalent mixture not containing it. It is therefore possible to delay the ignition of an air / fuel mixture by adding recycled gases to it until a maximum concentration limit beyond which the combustion of the fuel will be difficult and incomplete at the risk of producing polluting particles. .
- the proposed invention mainly relates to the management of the external EGR and to the process for controlling the flow of recycled gas admitted into the chamber to obtain the desired effects.
- the flow of recycled gas into the combustion chamber is controlled by a valve controlled by a computer.
- the quantity of fuel injected into the chamber is controlled by an injection pump controlled by this same computer.
- An air flow sensor located at the intake measures the amount of air admitted into the chamber.
- a sensor for measuring the air / fuel ratio of the exhaust gases is placed on the exhaust outlet so as to determine whether the fuel combustion is total or partial.
- the on-board computer increases the quantity of recycled gas in order to reduce the oxygen content of the oxidizing mixture and thus improve engine efficiency and reduce polluting emissions of nitric oxide due to an excess of active oxygen in the combustion chamber.
- This process for controlling the flow of recycled gases therefore makes it possible to improve the efficiency of the engine and reduce pollution by exhaust gases containing unburned fuels or nitrogen oxides.
- this process is based on the measurement of the air / fuel ratio of the exhaust gases.
- the air / fuel ratio is a partial indicator of engine operation and does not constitute a direct measure of engine performance, which is the primary measure for controlling an engine.
- the object of the present invention is to propose a method for controlling a heat engine making it possible to control the quantity of gas recycled in order to improve the efficiency of the engine.
- the method for controlling a heat engine of the invention is essentially characterized in that it further comprises a step of evaluation of a variation in engine efficiency over a completed period of time resulting from a variation of the control signal, and a step of updating the control signal, consisting in changing the control signal in a direction capable of maximizing the engine performance over a new time interval to come.
- This method according to the invention therefore consists in measuring or evaluating the variation in efficiency of the engine over a time interval and correlating this information with the variation in the control signal of the means for controlling the flow rate of recycled gases over this same interval.
- the control signal can be reduced for the new time interval to come so as to reduce the flow of recycled gas over the new interval compared to the flow of recycled gas during the past time interval.
- the rate of recycled gas in the room will be reduced and the rate active oxygen will be increased.
- the increase in the Air / fuel ratio correlatively induces better fuel combustion and therefore an increase in engine efficiency.
- the step of evaluating a variation in efficiency consists firstly in calculating engine efficiencies for first and second respective time intervals, the second time interval ending subsequently. at the first interval, each calculated yield corresponding to the ratio between the amount of work and the amount of fuel injected for each interval, then in a second step to calculate the algebraic sign of the ratio:
- FIG. 1 represents the method for optimizing the quantity of recycled gas admitted to a combustion chamber
- FIG. 2 represents a complementary method for optimizing the stratification in recycled gas admitted into a combustion chamber
- FIG. 3 represents a combustion engine having means for controlling the flow rate of recycled gases for each combustion chamber
- FIG. 4 represents a combustion engine having means for controlling the flow of recycled gases common to several combustion chambers.
- the invention relates to a method for controlling a heat engine with cyclic operation such as a direct injection diesel engine.
- ⁇ Figure 1 shows an embodiment of the method according to the invention. This process is a control loop allowing the flow rate and therefore the rate of burnt gases recycled in the combustion chamber to be adjusted in order to maximize the efficiency of the engine.
- the measurement time interval preferably corresponds to a number of motor cycles and the measurement is preferably averaged over several motor cycles in order to smooth the results of the measurements.
- the measurements of variation of the work performed by the engine and of variation of the quantity of fuel consumed over the time interval are transmitted to a computer which determines the variation or the average of the variation in efficiency.
- the efficiency R (n) of the engine for cycle n is obtained by the ratio between the torque Cpl (n) developed by the engine and the quantity of fuel Ti (n) injected during the cycle n.
- the calculated yield R (n) can also be corrected using a cartographic correction function F.
- This correction function F is a bijective relationship between a control state or an operating state of the engine and the correction to be applied to R (n).
- This function F varies according to known and previously measured environmental effects.
- this correction function F takes into account the sensitivity of the efficiency R to the command Com of flow rate in recycled gas.
- the relative work or torque Cpl (n) provided by a combustion chamber or by several chambers for a given cycle n is measured using a combustion chamber pressure sensor and / or an engine torque sensor placed on the crankshaft.
- This torque Cpl (n) can be calculated by measuring the force developed on the crankshaft or by measuring the acceleration of the crankshaft correlated with the gas pressure inside the chamber.
- the quantity of fuel consumed on a cycle n is noted Ti (n) and is measured directly with a flow meter and / or indirectly using the duration of control of the injector and the pressure of the injected fuel .
- the quantity of fuel calculated by indirect measurement can be corrected as a function of the fuel temperature and / or of the pressure inside the chamber.
- the computer determines the new control signal Com (n + 1) to be sent to the gas flow control means to be recycled for the cycle (n + 1) to come.
- the new value of the new control signal Com (n + 1) is a function of the ratio between the variation in efficiency measured between two successive motor cycles respectively called cycle p and cycle q.
- the variation in engine efficiency between cycle p and cycle q is calculated by subtracting the measured efficiency R (n-q) from the measured efficiency R (n-p).
- the variation in the value of the control signal between cycles p and q is calculated by subtracting the value of the Com (np) command to the value of the Com (nq) command.
- the new value of the new control signal Com (n + 1) is calculated by the ratio between the variation in engine efficiency and the variation in the control previously calculated.
- the new command Com (n + 1) is then transmitted to the recycled gas flow control means to adjust the flow of recycled gas during the cycle (n + 1) to come.
- This performance control process is repeated for subsequent engine cycles.
- the means for controlling the flow of recycled gas can be all or nothing or be continuously variable over a flow range from a zero flow to a maximum flow admissible by the engine.
- FIG. 2 represents a complementary method of carrying out the invention intended to keep the engine noise below a maximum admissible noise threshold.
- the combustion noise is linked to the combustion speed, that is to say the speed at which the energy resulting from the oxidation of the fuel by the oxidizer is released.
- the combustion chamber is supplied by at least two fluid streams each having a rate of recycled gas regulated by the flow control means and by the method described above. These two fluid streams feed a combustion chamber and thus form layers of fluids containing air and variable proportions of recycled gas.
- the rate of recycled gas of a stratum is a function of its rate of fuel load.
- Each fluid layer thus created has its own rate of recycled gas, and therefore its own ignition time and its own combustion speed which allows to spread the time of combustion throughout the chamber.
- the regulation of the recycled gas rates of each stratum and the differential of the recycled gas rate between the strata allows the combustion speed to be controlled and the combustion noise to be reduced.
- the method of FIG. 1 makes it possible to control the flow of recycled gases in order to maximize the efficiency of the engine and the method of FIG. 2 makes it possible to control the manner of admitting this recycled gas into the chamber and reducing the noise of the engine.
- the combination of these two methods therefore makes it possible to maximize the efficiency of the engine while controlling its noise level.
- the method of FIG. 2 consists in controlling the noise of the engine by a function called stratification or creation of fluid strata with recycled gas rate variable from one stratum to another.
- the closed-loop control method of FIG. 2 consists of a first step in the cycle n of measuring the noise Brm (n) emitted by the engine.
- the engine noise can be measured by any technique that can detect the combustion speed of the chamber. To do this, we can detect the time interval when the pressure inside the chamber rises suddenly. This measurement can in particular be carried out using a torque sensor transmitted by the crankshaft, using a pressure sensor inside the chamber by deriving the measured signals. This measurement can also be carried out using an accelerometer placed on the cylinder head or the crankshaft while looking for the maximum value of the acceleration.
- a second step of collecting information on the engine operating point is carried out during the same time interval as the noise measurement step Brm (n).
- the operating point corresponds mainly to the amount of fuel injected for a given engine speed.
- Other information on the engine operating point at cycle n can also be collected to determine an engine condition.
- a cartographic database serves as a reference to indicate what is the maximum permissible engine noise mapping Brc (n) corresponding to a state of the engine measured at cycle n.
- the computer compares the maximum admissible noise Brc (n) for the engine operating point at cycle n with the measured engine noise Brm (n) for this same cycle n.
- the computer increases the new stratification command value Str (n + 1) for the coming cycle n + 1 with respect to the value of the stratification command Str (n) of cycle n.
- the increase in the value of the stratification command makes it possible to create gas strata having different concentration levels of recycled gas and correspondingly different combustion rates. Combustion is therefore spread over time, which reduces engine noise.
- the computer reduces the new stratification command value Str (n + 1) for the coming cycle (n + 1) with respect to the value of the stratification command Str (n) of cycle n.
- the reduction in the value of the stratification command Str (n + 1) makes it possible to reduce the difference in concentration of recycled gases from each stratum of the chamber and correspondingly increase the rate of combustion.
- This noise control process can then be repeated for subsequent engine cycles.
- the stratification command for this process can be based on a single cycle n, or on an average of cycles, it can apply to the cycle immediately following the measurement or measurements, or be delayed by several cycles. It can also be applied room to room or on a set of rooms.
- the stratification function can be an all or nothing function or be a continuous variable function proportional to the difference between the measured noise Brm (n) and the mapping noise Brc (n).
- the two efficiency and noise control methods maximize output while limiting noise.
- FIGS. 3 and 4 respectively represent two examples of engines 30 and 60 provided with circuits for controlling the recycling of burnt gases for the implementation of at least one of the methods previously described.
- Each of these motors 30, 60 has three cylinders or combustion chambers 31, 32, 33.-
- Each chamber 31, 32, 33 comprises a fuel injector 51, 52, 53 as well as two intake inlets 34 to 39 respectively, separated from one another for introduce two separate fluid veins into each chamber.
- Each fluid stream can have a variable proportion over time of burnt gases recycled so as to form strata of gas in the chamber.
- the first, second and third combustion chambers 31, 32, 33 each have first and second burnt gas exhaust outlets 50 respectively 43 to 48. All of these exhaust outlets 43 to 48 are connected to an outlet main exhaust
- Each of the engines 30, 60 of FIGS. 3 and 4 is provided with a turbo 57 and with recycling means making it possible to collect a part of the exhaust gases 50 to introduce them at the level of the intake.
- the intake inlets 34 to 39 of the engine 30 of FIG. 3 are connected to a main intake 40 for the admission of air 41 and recycled burnt gases 42.
- the main intake 40 is itself connected to the main exhaust outlet 49 by means of a recycling 58 of burnt gases 42.
- the recycling means 30 comprises a control valve 59 for the rate of burnt gases recycled in the main intake 40. This valve 59 therefore makes it possible to control the flow of burnt gases for all of the intake inputs 34 to 39 and of the combustion chambers 31 to 33 and this by a single means of flow control.
- First, second and third stratification valves 54 to 56 respectively connect the means of recycling 58 of burnt gases to the second intake inlets 35, 37, and 39.
- Each of these three stratification valves 54 to 56 individually controls the stratification of each of the respective chambers 31 to 33.
- the first stratification valve 54 allows the admission of recycled gases into the fluid stream passing through the second intake inlet.
- the fluid stream passing through the second inlet 35 therefore has a variable rate of recycled gas. and controlled by the first stratification control valve 54 and / or by the rate control valve 59.
- the fluid stream passing through the first inlet 34 has a variable recycled gas rate which is only controlled by the rate control valve 59.
- the difference in concentration of recycled gases in the first chamber 31 can therefore be adjusted by acting on the first stratification valve 54.
- the motor 60 of FIG. 4 allows the simultaneous and centralized control for all the chambers of the flow of recycled gas as well as their stratifications.
- the engine 60 in this figure has first and second main intake inlets 61 and 62.
- the first and second main inlet inputs 61 and 62 are connected to the main outlet. exhaust 49 via a first recycling means 63 for the first main entrance 61 and a second recycling means 64 for the second main entrance 62.
- the first main inlet 61 is connected to the first intake inlets 34, 36, 38 thus allowing the admission of first fluid streams having the same concentration rate of recycled gases.
- the second main inlet 62 is connected to the second intake inlets 35, 37, 39 thus allowing the admission of second fluid streams having the same concentration of recycled gas concentration.
- the respective flows of recycled gas from the first and second main intake inlets 61 and 62 are independently and respectively controlled by first and second valves 65 and 66.
- This particular arrangement makes it possible to control the rate of gas recycled in all the chambers by two ' valves. These two valves also make it possible to control the stratification by acting on the differential flow rate of recycled gas 42 passing through the first and second recycling means 63 and 64.
- the means for controlling the flow rate of the recycled exhaust gases consist of valves controlled by at least one pneumatic, hydraulic or electric control means. These valves can deliver a continuous or discontinuous gas flow.
